A still further object of our invention is the'provision of a novel camarrangement for assisting operation of the delivery slide. A furtherobject of our invention is the provision of meansfor positivelyejecting'a coin from the delivery mechanism after it has served tounlock and permit movement of the delivery slide which carries articlesfrom the magazine. I

Another object of our inventionis the provision of a novel lockingdevice for the delivery slide that it adapted to be unlocked to releasethe delivery slide by the insert-ion'of a coin of the correctdenomination.

Other important features of our invention reside inrthe means foreliminating friction between the base and the delivery slide; the mannerof securing the closure plate to the base to prevent removal of coinstherefrom; and the general design and assembly of the different parts ofthe complete ma chine.

In the drawings, ournovel vending machine is shown as comprising threeprincipal parts which may be respectively designated as the base,vending mechanism and article containing magazine.

theoperation of the machine as a whole explanned to make clear theinteraction of the several parts. i

The base 1 comprises the walls 2, a top 3 and a removable bottom plate4, The base lforms a coin receiving receptacle and is provided with theremovable bottom plate for permitting access thereto. The bottom plate41s preferably provided with a plurality of resilientleg cushions 5 thatare secured within suitable sockets 6. It also, has

flanges 7 and 8 which are designed to interfit with the bottomsof thewalls 2 of the base to prevent removal'of coins; and alock 9 forattaching the bottom plate to the base. The end walls of the base arepreferably formed with projections 10 which the socket '11 and thetongue 12 of the lock 9 engage to hold the bottom plate 4 in position.It will be noted that the bottom plate 4 is of such construction thatthe removal of coins from the base is effectively prevented; and thatthe resilient leg cushions are a safeguard against damage'to any surfaceupon which the machine may rest. Accumulated coins may be removed fromthe base by detaching the bottom plated after unlocking'the lock 9. g

Secured to the'undersideof the top 3 of: base 1 is abracket 13. pivotedthereto a detent 14.- by means of screw 15. The detent 14 has a portion16 that projects above the top 3 as shown in Figures 1 and 4. Thisdetent is also formed with a recessed end 17 which fits in between twoguides 1'7 formed on the front wall 2 for a. purpose to be hereafterexplained. The detent 14: is normallyheld in the position indicated inFigures 1 and 41 by means of a q Each of these parts W'lll be separatelydescribed below and then This bracket has depending portion 19 of thedetent and at the other end to a pin 20 carried by the bracket 13. V

The delivery slide 21 is carried by the top 3 .of base 1 and is.reciprocable with reference thereto. As particularly shown in purpose ofthese knobs is to reduce friction and make for easier operation of thedo liveryslide'. Centrally of the bottom of the delivery slide andadjacent one edge thereof is formed a depending portion 26 which hasioppositely inclined faces 27 and 28 and subs'tantiallyv verticalsides29 and 30. The depending port-ion 26 also carries a pin. 31 thatconstitutes the means for positively ejecting a coin after the releaseand operation .of the delivery slide. The slide 21 is further formedwith an element 32 which has the oppositely inclined end portions thepurpose of which will hereafter appear. A post34 projects from thebottom of slide 21 and is adapted to cooperate with the locating camhereafter described. A pawl 35 is pivoted .to the slide21 (see Figure 5)and this pawl ,'.is normally held in the position shown in Figure .5 bya spring 36 whichis connected at oneend to a fixed pin 37 and attheother end toa projecting car 38 formed on one sideof the pawl. Thepurpose and operation of the .parts just described will be explainedhereinafter.

he top3 vof base 1 is preferably formed adjacentone side and integralwith one wall with the upstanding flange or guide members 39 and 40.These members are preferablyrecessed-as at .41 and 42 to form a coinretaining opening which in combination with the recessed portion 17 ofdetent 14 supports a coin in operative relation to the vending mechanismin themanner hereafter described. To .the top .3 of base 1 is alsopivoted a locating cam 43 which can be positioned as shown in Figure4,"but which normally tends to move laterally under the influence of atension spring 44 that is connected atone end to the fixed post 45 andat its other end to the tongue 46 on the locating cam. The locating cam43 is preferably provided with the forks 47 and 4 and when the deliveryslide is in position, these forks straddle the post 34. Thus, an initialmovement of the delivery slide post i 34 past the center position of cam43 will be positivelycompletedby the spring 44 without furtherassistance from the operator. Also, when the delivery slide beginsmovement the pawl 35 will engage or co-act with slide after partialoperation thereof.

The magazine 50 consists of side walls 51 and a back wall 52 and tothese walls are secured a top 53 and a bottom frame 54. The bottom frame54 is provided with a transverse member 55 and to this member aresecured the upright guides 56 by means of bolts 57, The bottom frame 54may be secured'to the base 1 by means of screws 58 which extend throughopenings 59 formed in the base 1 and engage with suitable threadedsockets formed in the frame 54. The front of magazine 50 consists of aremovable plate 60 which has side flanges 61 for overlapping the sidewalls 52. .The plate 60 may be secured to the 'front of magazine 50 bymeans of a lock 62 that .is adapted to engage with the top 53 and aprojection 63 that is designed to engage .in an opening 63 formed in thebase frame A plate 64 having a coin receiving opening 65 is attached toplate 60. 7'

The operation of my novel vending machine is as follows: i

The front plate 60 may be removed and the boxes of matches or otherpackages stacked on opposite sides of the guides 56. One of the stackswill rest in .one of the package receiving portions 24 ofthe deliveryslide 21, and the other stack will rest on the center elevatedportion'23 of the delivery slide 21. At this time the 'deliveryslidewill be locked by the portion 16 of detent 14 engaging against one ofthe vertical sides 29 or 30 (depending upon which end of the slideprojects from the machine) ofthe depending portion ,26 (Figure 2).Movement of the sliderand delivering of the articles from the magazinecan not be accomplished until a coin of the correct denomjina tion hasbeen placed in opening 65. Opening 65 communicates with. the vendingmechanism beneath, and a coin deposited therein will drop down andlodgein the recessed portion 17 of detent 14 and be retained therein bythe recesses 41and 42 in the-guides 39 and 40 (see F igure2). lVhen theprojecting end of the delivery slide 21'is pushed, the coin will firstbe wedgedbetween the recessed end 17 of detent 14 and one'of theinclined portions 33 of the element 32. As the movement ofthe slide'21is continued one or the other of the inclined portions 27 or 28 willcontact with .the portion 16 .of detent 13 and so' continue the downwardmovement thereof commenced by the inclined end portions of the "element32. Further movement of the delivery slide in thesame direction willdepress the portion 16 of detent 14 and allow one of the verticals'ides29 or 30 to passpart 16 when the coin will be forced beneath oneof theguidesc39 or 40by the continued movement of the slide. Ordi- Innnarily the element 32 will be suflicient to dis lodge the coin fromthevending mechanism but as an additional means for this purpose, thepin 31 is provided and this passes beneath the guides 39 and 40 and willpositively eject the coin in case it has not already been dislodged.During movement of the delivery slide in either direction the pawl 35will engage with the teeth of ratchet A9 and thereby prevent any reversemovement of the delivery slide until the stroke has been completed. Whenthe post 34 on the bottom of slide 21 has carried the locating cam 4L3beyond its center position, the spring 44 will contract and complete thestroke of the delivery slide without further assistance from theoperator. When the delivery slide has reached its extreme position anddelivered a package held in one of the package receiving portions 24 ofthe delivery slide, the pawl 35 will disengage from the ratchet 49 andturn under the influence of spring 46. It is understood that the pawl 35is always pulled over the teeth of ratchet 49 and therefore operates forboth directions of'movement of the delivery slide. The next operation ofthe machine is accomplished by inserting a coin in the usual manner andpushing the opposite or projecting end of the delivery slide. It will beunderstood that the delivery slide is moved alternately in oppositedirections to deliver packages from the different stacks of articles inthe magazine alternately.
